SHAFT LINE COMPONENTS

Simplex Sterntube Seals are propulsion shaft sealing systems that prevent oil leakage and water ingress, integrating with bearings and bushes to create complete sterntube solutions. Their reliability, low maintenance, and compliance with environmental regulations make them suitable for all types of vessels.

The range is complemented by Simplex Bulkhead Seals, self-lubricating bulkhead seals used on vessels with long shafts, and by Simplex Net Protector / Net Cutter / Net Pick-up solutions, which protect the aft seal from nets and floating debris. For dredgers and industrial vessels, Simplex Cutter & Pump Gear Bulkhead Seals provide specialized configurations to protect engine rooms and gear systems in demanding environments.

In addition, the range includes a wide selection of products such as:

1A. SIMPLEX Sterntube Seals

2A. SIMPLEX Shaft Line Bearings and Flexitube Sterntube Solutions

Included products:

  • Simplex shaft bearings

  • Simplex intermediate bearings

  • Simplex FlexiTube and SternTube

  • Simplex sterntube bushes

3A. SIMPLEX High-Load Thrust Bearings

4A. SIMPLEX BlueRun Sterntube Solutions

STABILIZERS

SKF stabilizers include both retractable and fixed models adapted to different types of vessels. The retractable S-type offers a compact solution for ferries, cruise ships, and yachts underway, while the Z-type adds zero-speed stabilization to maximize comfort on yachts and premium cruise vessels.

In fixed configuration, the FZ models stand out for their power and reliability without generating unbalanced forces, while the F models offer a proven and economical design for commercial vessels. For sustainable options, the fully electric and silent EFZ models are ideal for yachts and sensitive environments.
Overall, SKF stabilizers provide greater comfort, efficiency, and versatility for any hull type.

SKF RecondOil

Why is RecondOil the best solution for your fleet?

In a sector where efficiency and sustainability are no longer optional, RecondOil stands out as one of the most advanced solutions for intelligent onboard lubricant management. This technology enables continuous oil regeneration, preserving its original properties while minimizing consumption and waste generation.

 
 

For maritime operators and shipyards, incorporating RecondOil represents a true shift in the maintenance cycle: hydraulic equipment, engines, and critical systems operate with a cleaner and more stable lubricant, improving reliability and extending intervals between interventions. The result is a more cost-effective, safer operation with a significantly lower environmental impact.

Thanks to its commitment to high-performance solutions, Rolloy Marine facilitates the adoption of circular technologies such as RecondOil, helping fleets of all sizes move toward a more responsible maintenance model, extending oil service life and optimizing every hour of operation.

Turbulo Bilge water Separators

Turbulo provides a global maintenance service, original spare parts supply, and 24/7 technical support for its bilge water separators, suitable for both land-based facilities and maritime environments —including offshore platforms, power plants, and vessels. The service includes initial consulting, commissioning, regulatory compliance conversions, bilge alarm calibration, laboratory water and oil analysis, and urgent delivery of parts, ensuring that every unit operates consistently within required quality and certification standards.

Rotary Vane Steering Gear

What is the SKF Rotary Vane Steering Gear – V Series system?

The SKF Rotary Vane Steering Gear – V Series is a compact and highly reliable steering system designed for navy vessels. It incorporates a hydraulic unit with redundant pumps, integrated bearings, and a design ready to comply with SOLAS, IMO, and classification society requirements.

This system uses a stator–rotor–vane assembly, where hydraulic pressure acts to move the rudder with precision and smooth operation. Its design allows reaching ±35° or ±45° rudder angles, ensuring stable performance and low noise levels. The functional diagram in the document illustrates how the hydraulic flow is distributed through the rotor to generate rudder movement.

The V-Series offers a lightweight and compact design, a system of long-life seals, reduced wear on the lower rudder stock thanks to its robust radial bearing, and lower operating costs. In addition, it features easy installation (no bolts, only stopper welding) and allows fast maintenance without removing the stock or the hub, supported by 24/7 technical service.
